Thermal Spray Coatings
H.V.O.F. Thermal Spray Coatings
The Taskmaster High Velocity Oxygen Fuel thermal spray process provides High Density coatings with almost Negligible Porosity levels. This is a result of the high particle velocities produced by a combustion driven, high speed gas jet. HVOF is a supersonic process which delivers coating particles at over 7000 feet per second and can exceed bond strengths of 12,000 psi. It is an extremely versatile process that offers an unlimited range of possibilities to industries with extreme corrosion and wear environments such as Oil and Gas, chemical and refinery, agriculture, marine, hydroelectric plants, and pulp and paper mills.
If you need to maximize the life of your present or future equipment, then HVOF may be the answer to your particular problems. HVOF coatings are emerging as one of the most cost effective ways to replace other more environmentally hazardous coating processes such as industrial hard chrome plating.
Taskmaster Technologies Inc. offers a turnkey process, which includes robotic manipulation for control and accuracy, and years of experience in generating application procedures, that can save your company time and money. In addition, our finishing equipment allows us to meet very tight tolerance and surface finish requirements depending upon application specifications.
Flame Spray / Spray and Fuse
Taskmaster can provide traditional low velocity flame spray coatings for many applications. Alloys for general repair and build up as well as wear and corrosion resistance are readily available. Common alloys applied are aluminum bronze, stainless steels, and nickel or cobalt base.
Many products are also designed for a secondary fusing process ( spray and fuse ) giving the coating a very strong capillary bond similar to that of brazing and eliminating the inherent porosity of the "as sprayed" product. Common applications for this process are: pistons, plungers, thermowells, and washpipes.
Surface Blast / Shot peen
Surface blast preparation is a critical element of our coating application performance. In addition, Taskmaster can also provide blasting services for many other applications such as:
- Glass bead for surface decontamination or cleaning of corroded / dirty components.
- Grit Blasting with a variety of available grit sizes and materials to create a clean, rough surface profile that enhances grip and coating bond strength .
- Shot Peen from 110 to 780 grit sizes for stress relieving of surface tension on critical machined parts.
